What's new in 1.3 • Stream sensor data to any MQTT broker • USB serial output for Arduino/ESP32 via OTG • Webhooks with sensor thresholds • Record & export sensor data as CSV • Per-sensor sampling rates • Sensor preset profiles (built-in & custom) • Bluetooth auto-reconnect • New orientation (Euler angles) sensor • Resources screen with guides & code examples • Stability improvements Thanks for using SensorCast!
Stream live phone sensor data to ESP32, Arduino via BLE, WSS, USB & WiFi
SensorCast streams real-time sensor data from your Android device to ESP32, Raspberry Pi, Arduino, web dashboards, and any WebSocket client. It transforms your phone into a complete IoT sensor hub for prototyping, research, and data collection — no custom hardware needed. Unlike other sensor apps that only support WiFi, SensorCast offers dual transport: cloud streaming via WebSocket (Socket.IO) and local streaming via Bluetooth (BLE GATT + Classic SPP). Stream to one subscriber or hundreds simultaneously. Supported Sensors (40+): Motion: Accelerometer, Gyroscope, Linear Acceleration, Rotation Vector, Gravity Position: Magnetometer, Orientation, Game Rotation Vector Environment: Light, Pressure, Temperature, Humidity, Proximity Location: GPS (latitude, longitude, altitude, speed, bearing) Key Features: WebSocket streaming with JWT authentication and username-based routing Bluetooth BLE GATT for ESP32 and Classic SPP for HC-05, HC-06 4 output formats: JSON, CSV, Compact, Timestamp Custom field mapping with configurable decimal precision (0-6) Google OAuth 2.0 sign-in with AES-256 encrypted credentials Private and public stream modes with stream key protection Background foreground service with auto-reconnection Real-time gauges, data rate monitoring, and subscriber count Configurable sampling rate from 1 to 200 Hz Battery monitoring with per-sensor power estimates Built for IoT developers, researchers, educators, and makers. Use it for rapid IoT prototyping, ML training data collection, remote sensor monitoring, robotics, home automation, or classroom demonstrations.
